AdMob Ads Not Showing, No Impressions

[2MinLab]

Hi AdMob Support Team,

I am experiencing an issue with AdMob ads in my app.
Although my app has already been approved and is ready to show ads, the ads are not being displayed.
The ad requests seem to be sent, but no ads are returned (No Fill).

Could you please help me check the reason for this issue and guide me on how to resolve it?

If you need my App ID or Ad Unit IDs to check, please let me know and I will provide them.

Thanks, please help me.

We have the same problem with just 1 of our apps not getting TEST AD. Its always no fill error. It's an Android app that has been live for months and is receiving real ads. All our other apps are getting test ads.

To exclude any bugs in the implementation we used the admob banner sample app:
https://github.com/googleads/googleads-mobile-android-examples/tree/main/java/admob/BannerExample

We changed the manifest to our actual app:

<meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="ca-app-pub-XXXX"/>

The build.gradle to our actual app:

applicationId "xxx.xxx.xxx"  

And the ad unit ID to the test admob ID:
private static final String AD_UNIT_ID = "ca-app-pub-3940256099942544/6300978111";
from here https://developers.google.com/admob/android/test-ads

And we always get no fill, although test ads should always have a fill.

If we change the manifest meta-data and applicationId to one of our other apps, test ads works. All of our apps are showing "app-ads.txt file found and verified", "App verification Verified", "Approval status Ready" on the admob console.

I don't know if it's OK to share production admob app and ad unit ids on this forum, so the XXX values. Will gladly send these to admob support for testing

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

We understand you’re experiencing a no fill error for test ads on one of your Android apps, while other apps are receiving test ads correctly. To help us investigate further, could you please provide your app’s package name? This will allow us to review the specific setup and provide more targeted assistance.

Thanks,

Our Android app that is getting no fill on banner test ads, has the package name com.zombodroid.memegenplus

Have tried with fixed banner id ca-app-pub-3940256099942544/6300978111 and adaptive id ca-app-pub-3940256099942544/9214589741 Have also changed the manifest value for android:name="com.google.android.gms.ads.APPLICATION_ID". This has been tested on the github android java banner sample

Hi,

After checking the details you have shared, we have observed that you have not set up your app in AdMob. Please follow the setup an app in AdMob.

I would recommend checking a few additional resources to make sure all configurations are correct:

• Set up an app-ads.txt file for your app
• Make sure your package name is the same as what is registered to your app in your AdMob account. 
• Fully complete the setup of your AdMob account, particularly the billing and PIN verification sections.
• Link your app to your AdMob account; you may have to wait for a week or two after publishing an app in order to do this.
• Resolve any policy violations in your AdMob account.

Thanks,

The app com.zombodroid.memegenplus is setup with Admob. Our Admob account is multiple years old with multiple apps. This app has been live for months, test ads have worked for months. It's even receiving real ads and earning revenue.

We are still getting code 3 no fill for the banner test ad id ca-app-pub-3940256099942544/6300978111.

Se included screenshots from the Admob console.

Please check again.

Hi,

Thank you for getting back to us.

I have checked your AdMob account and found the app. I have executed our sample project utilizing the test IDs(ca-app-pub-3940xxxx2544/630xxxx11 and ca-app-pub-3940xxxxx42544/921xxxx41) and am able to load the ads. However, when the package name was updated to your specified package name (com.zombodroid.memegenplus), advertisements failed to load. This indicates that the issue lies with the package name itself. Upon further investigation, this seems to be an Ad serving concern rather than anything specific to the code implementation of the Mobile Ads SDK.

The best way to get more information about your issue is the AdMob Help Center. You can also utilize the AdMob Communities for additional support. 

Thanks,
